Abstract

La présente invention concerne un film étirable (1, 2) comprenant une couche d'élastomère (10) et des couches de surface (20, 22) disposées sur un côté ou les deux côtés d'une première surface (10a) et d'une seconde surface (10b) de la couche d'élastomère (10), les couches de surface (20, 22) comprenant chacune du carbonate de calcium et au moins une résine à base de polypropylène choisie dans le groupe constitué par un polypropylène séquencé qui est un copolymère avec de l'éthylène et un polypropylène aléatoire qui est un copolymère avec de l'éthylène ; la teneur du carbonate de calcium dans les couches de surface (20, 22) étant de 10 à 75 % en masse par rapport à la masse totale des couches de surface (20, 22) ; l'épaisseur de la couche d'élastomère (10) étant de 20-55 µm ; et l'épaisseur des couches de surface (20, 22) étant de 0,4 à 5,0 µm.
